Of course there is SOME loss, but my point was that its no where near the loss that is calculated in SAE correction factors!

terry: when are you going to dyno your "terry tuner"?
I'd agree that the higher boost cars are running out of compressor at higher elevations, but even the fastest stock car was running slower than stock cars run at sea level. The ECU raises boost to try to compensate, but it’s not 100%.

On the Terry Tuner, I might go this week. I'm not a huge fan of going to the dyno because it's a little expensive and I'd rather spend the time going to the track, but I'll bite the bullet for the betterment of e90forum.
